The invention relates to a marine steering engine of a two-stage mechanical transmission structure, and belongs to the technical field of ships. The marine steering engine comprises a driving device,speed reducers and a rudder rod which are sequentially connected and further comprises a support; the speed reducers comprise a first-stage speed reducer and a second-stage speed reducer; the first-stage speed reducer adopts pin shaft type output cycloidal planetary transmission; the second-stage speed reducer adopts 2K-V type cycloidal planetary transmission; an output end disc of the first-stagespeed reducer, an input shaft of the second-stage speed reducer and a center wheel are in integrated design; supporting bearings of a planet carrier of the first-stage speed reducer and an output planet carrier of the second-stage speed reducer adopt crossed roller bearings, outer rings are integrated on a needle tooth shell, and inner rings are integrated on corresponding end discs; and double eccentric support bearings on an input crank shaft in the first-stage speed reducer and an output crank shaft in the second-stage speed reducer are full complement cylindrical roller bearings. The device can directly bear the combined effects of torque, axial loads and bending loads, has strong impact resistance and is compact in structure, large in transmission speed ratio and high in transmissionefficiency.
Description
technical field [0001] The invention belongs to the technical field of ships and relates to a ship steering gear with a two-stage mechanical transmission structure. Background technique [0002] In the ship control system, the course control of the ship is the most basic control requirement. In order to realize the steering of the ship, the steering gear is generally arranged above the rudder. In order to bear the axial load and balance the axial impact, the existing steering gear needs to install buffer rubber, buffer frame and other structures, which makes the mechanism redundant; in addition, the existing hydraulic steering gear has low efficiency and requires large power consumption, which is harmful to the motor. Higher requirements. Contents of the invention [0003] In view of this, the purpose of this application is to provide a marine steering gear with a two-stage mechanical transmission structure, which can directly bear the comprehensive effect of torque, axi...
